Hello

Please find the solution in the attached file.

1.Find and label the vertex and the line of symmetry. Graph the function.

F(x)= 3(x-2)

Ans . : Compare this equation with X2 = 4A F(X)

Then we can see that

4A = 1/3 and X = x - 2

This implies A = 1/13

To find vertex of the function, equating F(X) and X equal to 0.

Thus we have

F(X) = 0 and x -2 = 0 this gives F(x) = 0 and x =2

Thus vertex is (2, 0).

Line of symmetry is x = 2 .
